The Smiths' most unloved fan, David Cameron, has issued a defiant pledge to continue listening to the band's music despite the latest edict by one of its members that he should cease doing so.

Speaking in India after guitarist Johnny Marr specifically ruled This Charming Man off-limits to the ears of the prime minister, Cameron was steadfast in his desire to remain devoted to the band despite the prohibition.

"I have now got both Johnny Marr and other members of the band saying I'm not able to listen to the Smiths," he told the BBC.

"When I've got the full set, even then I'm afraid I will go on listening to them."

In his latest "ban" on Cameron liking the music of the Smiths, who split in 1987, Marr singled out This Charming Man, a single chosen by Cameron on Desert Island Discs.

Marr told Radio 4's Today programme: "I think he likes the song. That's probably sadder than if he didn't know it, really. He's entitled to like whatever he likes, as long as he doesn't say it. It's a good song." "I do forbid him to like it. He shouldn't like us because we're not his kind of people."
